Convert the sh architecture to make use of the new asm-generic/io.h to
provide address mapping functions. As the generic implementations are
suitable for sh this is primarily a matter of moving code.

Feedback from architecture maintainers is welcome.

I'll try to find time and test this change on top of my fixes
during the weekend.


Feedback from architecture maintainers is welcome.


The unmodified U-boot from the last two releases can not run
on any SH board, you can consider that SH arch is unmaintained.

Convert the sh architecture to make use of the new asm-generic/io.h to
provide address mapping functions. As the generic implementations are
suitable for sh this is primarily a matter of moving code.
